Confusion of 'pastor' title across churches — example of 8 different pastor titles

Uses a local church example with 8 different 'pastor' titles: pastor of assimilation, worship and digital media, leadership development and small groups, worship and service production, pastor of women, etc. Half of these positions are held by women. If 'pastor' means 'elder,' these women are violating scripture. But these roles may not actually be elder functions at all. Terms must be defined before answering whether women can be 'pastors.'
